Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31513710, here are decompositions:

13 + 31513697 = 31513710
17 + 31513693 = 31513710
43 + 31513667 = 31513710
89 + 31513621 = 31513710
97 + 31513613 = 31513710
103 + 31513607 = 31513710
131 + 31513579 = 31513710
149 + 31513561 = 31513710

Showing the first eight; more decompositions exist.
